Chinese researchers have produced the largest virtual universe on Sunway TaihuLight, the world's fastest supercomputer, using 10 trillion digital particles. The simulation beat the scale of the previous European record-holding model universe by a factor of five.

Gao Liang at the Chinese Academy of Sciences says Sunway employed 10 million central-processing unit cores, running multiple instructions on each core to accelerate calculations. Gao also notes Sunway remained stable at its peak performance.

Sun Yat-sen University professor Lin Weipeng says Sunway's physical architecture and its home-grown chip required Gao's group to write most of the software from the bottom up.

The Sunway simulation could only be maintained for about 60 minutes, while the University of Zurich in Switzerland's universe model ran for 80 hours. Still, Lin says the achievement is a significant milestone, one that "will allow China to take full advantage of its hardware superiority and stay on top in the [supercomputing] race."
